f HEINFORCING DEVICE FOR CONCRETE STRUCTURES.

Specification of Letters Patent.

Patented Jan. 16, 1906.

Application filed March 17,1905. Serial No. 250,571.

:was iireprooi structures or buildings, and ,particularly buildings otthis class whichv einplcv columns, beams, girders, and the like composedoi concrete reinforced with steel bars, ties, or other devices oivarious kinds and classes which are embedded in the concrete material;and the object of the iiivention is to provide an improved reinforcingor strengthening device for use in structures of the class speciiied4and which-may be einployed in columns, beams, and girders coinposedofconcrete or similar material and which may also be employed in Vfloor and ceiling construction or in making slabs or -plates of any size.

The invention is fully disclosed in the following specification, ofwhich the accompanying vdrawings form a part, in which theseparater-parts of my improvement are designated by'suitable referencecharacters in each of the views, and in which- Figure 1 is a side viewof a reinforcing device of the class speciiied made according to myinvention, parts being sectioned; Fig. 2, a section on the line 2 2 ofFig. 1 Fig. 3, a view similar to Fig. l, but showing a mod iiication;Fig. 4, a section on the line 4 4 of Fig. 3; Fig. 5', a view similar toFig. l, but showing another modification; and Fig. 6, a section on theline 6 6 of Fig. .5.

in the practice of' my'invention as shown in Figs. 1 and 2 rovide twoparallel bars c and the bar a in t ie form of construction shown beingcomposed oi" channel-iron and the barb being an ordinary T-bar, andthese bars are connected and at the saine time separated to apredetermined extent by binding-rods c, which are arranged diagonallyand in oppo- 'site` directions and which cross each ot ierlongitudinally of the center space between said-bars. In the form ofconstruction shown the rods c are continuous and the bara is provided atintervals with longitudinal slots or openings a2 andthe bar b withcorresponding slots or openings 02, which ai'e punched therein from theinner side outwari'lly in the process of making said bars or after thebars have been made, as may be desired, and the binding-rods c arelpassed through the slots or openings and form on the outer sides oftht` bars a and b loops c?, through which are passed key pins or wedgesc, which may be ol" any desired shape and size, and in the4 processorforiiiiiig or punching the slots or openings a? and J" correspondingoutwardlydirected lugs, ears, or projections a3 and b are lornied on theouter sides of the bars uA and b and at the opposite ends of the slotsor openings c2 and bi; but the lugs, ears, or projections ci and l)3 arenot an essential feature and may or may not be employed; but said lugs,ears, or projections when formed in the 'manner described giveadditional strength to the reinforcing device comprising the parallelbars a and b and the longitudinally-arrangcd binding-rods c, whichconnect said bars in thel manner described. lYlien the bars c, and l)have been connected in the mannerdescribed, they form a rigidtruss'work, the bars of which cannot be pressed together or separated,and iii practice a reinforcing device oi this kind may be placed in acolumn or in a beam or girder, or a number of them may be. placedparallel in the floor and ceiling construction, composed of concrete orsimilar material, and in all of these cases the concreto Aor similarmaterial entirely incloses the reinforcing device, as indicated by thedotted lines in Figs. l and 2.`

In Figs. 3 and -l l have shown a modification in which parallel bars dare employed, said bars being composed of ordinaryv channel-iron, andpassed through the side walls thereof at regular intervals are pins d2,and binding-rods c, similar to those shown in Figs. 1 and 2, areemployed for connect-ing the parallel bars d, and in-tliis operation thebinding-rods are passed around the oppositelyarranged pins d and inopposite directions and crossing each other between said pins and at thecenter of the space between the bars d, the binding-rods c being alsocontinuous, as in Figs. 1 and 2. This arrangement of the bindin -rods cfirmly connects the bars d and also holds them at a suitable distanceapart, and a comparatively strong and staple reinforcing device is thusformed, and in practice this device is embedded in concrete. either inthe form of columns, beams, or girders IOO or in floor 'and ceilingconstruction, or wherever it may be desired, in the saine manner as withthe coi'istruct-ion shown in Figs. l and 2.

ln Figs. 5 and l have shown another modification, which is siniilar'inall respects to that shown in Figs. l and 2, except that instead 'offorniingone slot or opening at the points Where the biiiding-rodsc`connect Witl'..

the bars a and l) tivo holes e are formed, and the bindiiig-rods c arepassed through these holes, and these sepa-rate holes form a web portionor 'tongue over or around Wlhich the i floor and ceiling construction orin slabs a number of them may be placed parallel With each other andbound together by'horizon'tal rods, thus making a horizontaltrestle-Work, and this method may also be employed in making verticalWalls, and it Will be understood that in employing columns, beams,girders, and the like in structural Work the ends ol? said columns,beams, girders, and the like will be provided Withthe usual means ofconnection and supports. y

Although I have shown but tWo forms of bars-namely, channel-iron andT-iron-in the various forms of reinforcing or strengthening devicesherein shown and described, it will be apparent that the parallel sidebars may be made in any desired sha-pe in crosssection. i

ln addition to the uses herein specified for my improved reinforcingdevice the same may also be used in railway ties, sleepers, and thelike, and it will also be apparent that a structure of this kind may beemploved in certain relations or Wherever such devices are required. i f

Having fully described my inveiition,what

stesse l claim as new, and desire to secure by Leting parallel side barsand connecting-rods arranged diagonallyv between said ars and crossingeach other at regularintervals eenm trally and longitudinallybetiveensaid bars, said connecting-rods being connected with said harsso as to prevent their outward ,and inward movement, and saidconnecting-rods being continuous, substantially as shown and described.
